MBC’s upcoming drama “Crushology 101” has unveiled a new teaser!

Based on a popular webtoon, “Crushology 101” is a romance drama following the journey of college student Ban Hee Jin (Roh Jeong Eui), who is nicknamed “Bunny.” After her disastrous first relationship ends badly, Ban Hee Jin unexpectedly finds herself entangled with multiple handsome men that suddenly approach her.

The newly released teaser showcases each of these men as they try to win Ban Hee Jin’s heart with their unique charm.

It opens with Ban Hee Jin’s excited voice saying, “My first boyfriend is…” Against the backdrop of a campus in full bloom, with cherry blossoms drifting like popcorn, she smiles brightly and waves, calling out, “Oppa!” The scene leaves viewers wondering which man she’s addressing—Hwang Jae Yeol (Lee Chae Min), Cha Ji Won (Cho Jun Young), Cho A Rang (Kim Hyun Jin), or Jin Hyun Oh (Hong Min Ki).

Ban Hee Jin describes her relationship with Hwang Jae Yeol as a “debtor-creditor relationship.” As they repeatedly get caught up in unpleasant situations, she even vows, “I should never get involved with someone like him.” But despite their constant bickering, their connection grows. Hwang Jae Yeol’s cryptic remark—“Do you really don’t know why I’m acting like this?”—adds to the tension, leaving viewers’ hearts fluttering.

Among the strong contenders, Cha Ji Won stands out for his warmth and thoughtfulness. Impressed by his kindness, Ban Hee Jin says, “Is it even fair for someone that good-looking to be this sweet too?” He then locks eyes with her and replies, “I’m not like this with just anyone,” leaving Ban Hee Jin even more conflicted.

Cho A Rang’s flirtatious charm is undeniable. From saying, “Do you remember the title of the piece we saw earlier? It was ‘Fate,’” to casually asking, “Bunny, do you have a moment?” he openly expresses his interest, drawing viewers deeper into the romance.

Despite his charismatic demeanor, Jin Hyun Oh shyly confesses, “I’ve never really been into anything besides sports—except for my first love.” His heartfelt admission melts hearts, while he playfully teases Ban Hee Jin, making the moment even more endearing.

As the four men compete for Ban Hee Jin’s heart with their irresistible charm, curiosity builds. Will she choose the sharp and cunning Hwang Jae Yeol, the loyal and dependable Cha Ji Won, the sweet and charming Cho A Rang, or the bold and daring Jin Hyun Oh?
